I fail to see what the problem is if the node is a router that has a global on one interface and a site-local one on another interface.
If you have a site-border router in two sites, and the hosts in one of the sites _only_ have site-local addresses, then you don't need a router at all, as it will never forward any packets.
The hosts in the site that only has site-local addresses will not be able to send any packets outside the site, and no hosts from outside the site will be able to send any packets to them.
